Quality programs are frequently implemented with the aim of identifying clinical deterioration and reducing avoidable mortality. However, low rates of inpatient mortality with a diverse etiology make quantifying cost savings from avoidable mortality reduction challenging. To establish a relationship between mortality and length of stay, a commonly accepted indicator of hospital cost, we evaluated total hospital and intensive care unit length of stay for inpatients who expired compared to similar patients who did not expire during their hospital stay. Methods We conducted a retrospective propensity-matched cohort analysis of hospital inpatients who did and did not expire using de-identified data from 24 hospitals representing six health systems across the United States. In addition to demographic measures, the Rothman Index patient condition score was used to ensure cohorts were matched in physiologic acuity. Multivariable regression models were used to estimate the impact of mortality on the primary outcomes of total and ICU length of stay. Results Matched cohorts of patients who did and did not expire each comprised 6,129 patients. Patients who expired had longer mean overall hospital length of stay (LOS) compared to those who did not (13.3 vs 8.3 days, p < 0.0001) as well as longer mean ICU LOS (7.2 vs 5.7 days, p < 0.0265). Multivariable general linear models identified a 51% increase in predicted LOS and 33% increase in ICU LOS for patients who expired in the hospital. Conclusion As length of stay measures are routinely quantified in financial terms by hospitals, this work suggests it may be possible to translate mortality reductions into length of stay reductions as an inferential step in deriving a financial return on investment for mortality-focused quality of care initiatives. Mortality Length of Stay Return on Investment Quality Improvement Early Warning Score System Figures Figure 1 Introduction Hospital quality initiatives often include a focus on avoidable mortality, reflecting measures that the Centers for Medicare and Medicaid Services, the Joint Commission, and the Agency for Healthcare Research and Quality have emphasized in quality-of-care assessments. 1 One area of focus to reduce avoidable mortality is timely identification of, and response to, clinical deterioration. 2 , 3 In support of these efforts, hospitals are increasingly investing in the implementation of early warning score (EWS) systems, which commonly report performance for mortality risk prediction 4 – 6 and which have been successfully incorporated into clinical processes to reduce mortality, 7 – 11 although consistent benefit from EWS deployments remains unclear. 12 However, operationalization of EWS technologies and associated care delivery processes entails significant expense; these include information technology and software technology costs, technical and informatics resources to set-up and maintain EWS systems, clinical care redesign efforts, end-user training and support, and the cost of time taken by end-users to review and interpret the EWS output. 13 Such investments face scrutiny given that widespread challenges in hospital financial performance 14 have increased pressure to demonstrate that hospital quality programs will yield a positive financial return on investment (ROI), despite this often being a difficult measure to quantify. 15 , 16 Directly calculating the ROI attributable to mortality reduction initiatives ideally involves a comparison of costs between patients who expire but could have been intervened on (“potentially avoidable mortalities”, sometimes termed failure to rescue 17 ) and a similar group who would have likely died without the interventions prompted by the initiative (“successfully avoided mortalities”). However, the relatively low rate of avoidable mortality 18 and the wide variation in diagnoses, medication and treatment plans, as well as non-clinical factors (e.g., patient-dictated goals of care and the influences of administrative and insurance status considerations) confound basic analyses seeking to generalize the costs of care associated with patient mortality. In contrast, overall patient length of stay (LOS) and intensive care unit (ICU) length of stay are both closely connected to costs of care and management of LOS is strongly associated with management of costs. 19 Varying methodologies are used to calculate the unit cost per day of hospitalization or unit cost per ICU day but these are nevertheless commonly reported Figs. 2 0–22 and numerous studies have shown that the primary cost driver in the ICU is LOS. 23 Therefore, to establish an approach for quantifying the ROI associated with inpatient mortality reduction we sought to elucidate the relationship between mortality and both overall as well as ICU LOS to understand if changes in mortality could be extrapolated to changes in LOS as a basis for estimating financial impact. Methods We conducted a retrospective propensity-matched cohort analysis in accordance with STROBE guidelines 24 using de-identified data for inpatients discharged between January 1, 2022 and October 31, 2023 from 24 hospitals across six health systems. Hospitals ranged from a 24-bed critical access hospital to a 1,500-bed academic medical center and represented six states from the west coast, mid-west, southwest, southeast, and northeast United States. Inclusion criteria were patients 18 years of age or older admitted to either a routine or intermediate care unit. Patients directly admitted to an ICU were excluded to focus on patients with an opportunity to deteriorate or who were more likely to constitute avoidable mortalities – the primary target of general EWS systems. 5 Patients discharged to hospice and patients without a Rothman Index (RI) score (Spacelabs Healthcare, Snoqualmie, WA) during their stay were also excluded from the analysis. Administrative discharge codes were used to identify inpatient mortality and discharge to hospice. Outcomes of interest were overall inpatient LOS and ICU LOS, both calculated using Admission, Discharge and Transfer system data from health system electronic medical record systems. Propensity matching was used to control for differences across cohorts. 25 – 27 Matching covariates included patient age and sex as well as the first RI score during the visit. The RI, a widely validated, commercially available machine learning-based score of patient condition was used to control for differences in physiologic acuity. 28 Previous studies have shown the RI to be well-calibrated across the spectrum of patient acuity and effective at stratifying patient risk. 29 , 30 Logistic regression techniques were used to identify the cumulative probability of mortality using the matching covariates. Cases of patients who expired were then matched to controls based on these probabilities using a 1:1 Greedy matching algorithm. This algorithm attempts to match cases with the highest precision match first and continues to perform matches until no additional matches are found thereby minimizing the number of incomplete and inexact matches. 31 Matching processes were conducted separately for all six health systems and the post-match data was combined across all facilities for analysis. Baseline demographics including patient characteristics (e.g., sex, age, race, ethnicity), visit characteristics (e.g., admit type, discharge status) and clinical features representing clinical status (e.g., first RI score, surgery during stay) were reported and compared across cohorts before and after the matching process. Counts and percentages were used to report and compare categorical outcomes across cohorts while mean, median, and standard deviation were used to compare continuous variables such as overall and ICU specific LOS. Chi-square tests were used to analyze differences between cohorts for categorical variables with Fisher’s exact test used for comparisons with small sample sizes. For continuous variables, ANOVA was used to analyze differences between cohorts with Mann-Whitney tests used for non-normal distributions. Multivariable regression models were used to estimate the impact of mortality on study outcomes. General linear regression models with negative binomial distributions were used to evaluate both overall LOS and ICU specific LOS. Model covariates included patient and visit characteristics and clinical features indicating severity of illness and physiological status. All statistical tests were conducted using SAS version 9.4 (SAS Institute, Cary, NC). Alpha was set at 0.05 for tests of significance. Results Our study population (Fig. 1 ) included 493,105 patients 18 years old and above. Of these, 12,165 were excluded as hospice discharges, a further 44,017 were excluded as direct ICU admits, and 54,441 were excluded due to not having RI scores. The final study population consisted of 382,482 adult inpatients with a mortality rate of 1.9% Within this population, patients who expired were older (74.2 vs 59.1 years old, p < 0.0001) and had lower RI scores upon admission to the hospital (x̄ = 46.9 vs x̄ = 75.0, p < 0.0001) and were less likely to have surgery during their stay (8.7% vs 13.4%, p < 0.0001). The study cohorts were stratified by propensity matching into two equal groups of 6,129 patients. Table 1 reports the patient demographic, visit, and clinical characteristics of the study population prior to and after the matching process. As shown in Table 2 , patients who expired had longer mean overall hospital LOS (13.3 vs 8.3 days, p < 0.0001) as well as longer median LOS (8.1 vs 5.1 days, p < 0.0001) compared to those who did not. ICU specific LOS was significantly longer when comparing mean ICU LOS across cohorts (7.2 vs 5.7 days, p < 0.0265), however this difference was not statistically significant when evaluating median LOS (3.6 vs 3.2 days, p = 0.6416).

Other factors associated with longer total LOS included urgent (IRR = 1.380, 95% CI = 1.246–1.530, p < 0.0001) and emergency admissions (IRR = 1.152, 95% CI = 1.091–1.216, p < 0.0001) as well as surgery occurring during the hospital stay (IRR = 1.953, 95% CI = 1.852–2.059, p < 0.0001). Factors associated with shorter hospital LOS were female sex (IRR = 0.922 (0.893–0.951, p < 0.0001), higher RI scores which represent lower acuity (IRR = 0.997, 95% CI = 0.996–0.998, p < 0.0001) and higher ages (IRR = 0.989, 95% CI = 0.987–0.990, p < 0.0001).

Specifically, we evaluated patients admitted to lower level of care settings, a population targeted by many mortality reduction programs including those using EWS 5 . We found that patients who expired had significantly longer LOS, both overall and in the ICU. We also found that patients with urgent and emergency admissions, as well as surgical procedures, had longer LOS, and the latter two factors were also associated with longer ICU LOS. Complexity of correlations between mortality and LOS have been reported elsewhere, and causal relationships and interacting clinical considerations are not simple to delineate. 32 In light of the range of factors associated with LOS measures, a strength of our analysis is its patient-level nature 33 and use of the RI to ensure cohorts were of comparable acuity at the time of admission to account for the relation between baseline physiological acuity and mortality risk. 1 , 34 Individual hospitals may find that the magnitude of the LOS difference between expired and non-expired patients in their populations is different from what we report here, and indeed additional matching criteria may be considered for deriving comparison cohorts. However, the magnitude of the difference we have found in both overall and ICU LOS for patients with comparable physiologic acuity on admission as measured by the RI patient condition score strongly suggests that a non-negligible LOS difference exists. Hospital-based quality improvement initiatives face a growing need to demonstrate a robust business case justification and an argument for cost effectiveness. In particular, quality initiatives that require significant investment, such as operationalizing EWS for more timely detection and intervention on deteriorating patients, can have laudable quality goals yet struggle to translate even unambiguous success into a clear financial benefit. Hence, we posit that a rigorously established association between mortality and LOS may provide a means for organizations to extrapolate a reduction in both overall and ICU LOS from reductions in inpatient mortality. This would then allow readily available cost-per-day models to be brought to bear for the purpose of computing a financial ROI attributable to a reduction in avoidable mortality. Furthermore, we note that the ability to infer a reduction in LOS from a reduction in avoidable mortality circumvents two associated LOS measurement challenges. First, while the LOS savings from a program focused on reducing avoidable mortality may be substantial within the specific target population, the volume of this target population (deaths and avoided deaths) is small (typically a few percent) relative to the total acute-care population, making it quantitatively challenging to discern an LOS change due to mortality reduction initiatives within total population-level LOS statistics. Second, variations in population acuity over time (which may be as simple as a more severe flu season from one year to another), variations in populations served (e.g. shifts in regional acute-care capacity, staffing and specialty service capacity, inter-hospital transfer patterns, ambulance diversion rates, etc.) and the fact that multiple contemporaneous operational changes are frequently made which have the potential, if not explicit aim, of influencing LOS, make causal attribution of changes to population-level LOS an uncertain proposition. Identifying and isolating initiatives likely to bear on mortality rates is a more manageable task, while possible acuity changes in a focused population can be accounted for using risk adjustment or acuity matching methodologies. Our study has limitations. We lacked data on patient goals of care, comfort measure status, and advanced directives which, if included as covariates, could nuance the populations used in the matched cohorts. We did not include diagnosis in the analysis, and while the Rothman Index was built and validated as a diagnosis agnostic patient condition acuity score, we recognize that at a granular patient level the course of care, decisions related to treatment in the ICU, and overall LOS may have a dependence on diagnosis and comorbidities. Additionally, while we conducted the matching process separately for each health system, combining data in the final analysis may have obscured facility-level differences in LOS measures between cohorts. We anticipate future work will entail expanding the methodological approach presented in this work to include segmenting populations by clinical diagnosis and/or comorbidities. Extending our analysis to evaluate the costs of care (or cost-per-day) specific to the patient sub-populations in our matched cohort groups may also elucidate important differences between generalized cost-per-day figures and the costs pertaining to our analysis populations (i.e. average costs are likely to be different in selected sub-population as a function of variations in acuity, treatment plans, goals of care etc.). Conclusions Financial pressures increasingly require that quality initiatives demonstrate a positive ROI. Reducing avoidable mortality is a well-established quality of care goal, but one which requires an investment of resources that is not straightforward to justify on a purely financial basis. This work demonstrates a statistically rigorous approach to inferring LOS reductions from mortality reductions as a possible path to calculating a financial ROI for programs that are successful in their quest to improve avoidable mortality rates.

mortality, our study sought to understand the association of mortality with overall LOS and ICU LOS.

We also found that patients with urgent and emergency admissions, as well as surgical procedures, had longer LOS, and the latter two factors were also associated with longer ICU LOS. Complexity of correlations between mortality and LOS have been reported elsewhere, and causal relationships and interacting clinical considerations are not simple to delineate.\u003csup\u003e\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e\u003c/sup\u003e In light of the range of factors associated with LOS measures, a strength of our analysis is its patient-level nature\u003csup\u003e\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e\u003c/sup\u003e and use of the RI to ensure cohorts were of comparable acuity at the time of admission to account for the relation between baseline physiological acuity and mortality risk.\u003csup\u003e\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e,\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e\u003c/sup\u003e\u003c/p\u003e \u003cp\u003eIndividual hospitals may find that the magnitude of the LOS difference between expired and non-expired patients in their populations is different from what we report here, and indeed additional matching criteria may be considered for deriving comparison cohorts. However, the magnitude of the difference we have found in both overall and ICU LOS for patients with comparable physiologic acuity on admission as measured by the RI patient condition score strongly suggests that a non-negligible LOS difference exists.\u003c/p\u003e \u003cp\u003eHospital-based quality improvement initiatives face a growing need to demonstrate a robust business case justification and an argument for cost effectiveness. In particular, quality initiatives that require significant investment, such as operationalizing EWS for more timely detection and intervention on deteriorating patients, can have laudable quality goals yet struggle to translate even unambiguous success into a clear financial benefit. Hence, we posit that a rigorously established association between mortality and LOS may provide a means for organizations to extrapolate a reduction in both overall and ICU LOS from reductions in inpatient mortality. This would then allow readily available cost-per-day models to be brought to bear for the purpose of computing a financial ROI attributable to a reduction in avoidable mortality.\u003c/p\u003e \u003cp\u003eFurthermore, we note that the ability to infer a reduction in LOS from a reduction in avoidable mortality circumvents two associated LOS measurement challenges. First, while the LOS savings from a program focused on reducing avoidable mortality may be substantial within the specific target population, the volume of this target population (deaths and avoided deaths) is small (typically a few percent) relative to the total acute-care population, making it quantitatively challenging to discern an LOS change due to mortality reduction initiatives within total population-level LOS statistics. Second, variations in population acuity over time (which may be as simple as a more severe flu season from one year to another), variations in populations served (e.g. shifts in regional acute-care capacity, staffing and specialty service capacity, inter-hospital transfer patterns, ambulance diversion rates, etc.) and the fact that multiple contemporaneous operational changes are frequently made which have the potential, if not explicit aim, of influencing LOS, make causal attribution of changes to population-level LOS an uncertain proposition. Identifying and isolating initiatives likely to bear on mortality rates is a more manageable task, while possible acuity changes in a focused population can be accounted for using risk adjustment or acuity matching methodologies.\u003c/p\u003e \u003cp\u003eOur study has limitations. We lacked data on patient goals of care, comfort measure status, and advanced directives which, if included as covariates, could nuance the populations used in the matched cohorts. We did not include diagnosis in the analysis, and while the Rothman Index was built and validated as a diagnosis agnostic patient condition acuity score, we recognize that at a granular patient level the course of care, decisions related to treatment in the ICU, and overall LOS may have a dependence on diagnosis and comorbidities. Additionally, while we conducted the matching process separately for each health system, combining data in the final analysis may have obscured facility-level differences in LOS measures between cohorts.\u003c/p\u003e \u003cp\u003eWe anticipate future work will entail expanding the methodological approach presented in this work to include segmenting populations by clinical diagnosis and/or comorbidities. Extending our analysis to evaluate the costs of care (or cost-per-day) specific to the patient sub-populations in our matched cohort groups may also elucidate important differences between generalized cost-per-day figures and the costs pertaining to our analysis populations (i.e. average costs are likely to be different in selected sub-population as a function of variations in acuity, treatment plans, goals of care etc.).\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eFinancial pressures increasingly require that quality initiatives demonstrate a positive ROI.

Quality programs are frequently implemented with the aim of identifying clinical deterioration and reducing avoidable mortality. However, low rates of inpatient mortality with a diverse etiology make quantifying cost savings from avoidable mortality reduction challenging. To establish a relationship between mortality and length of stay, a commonly accepted indicator of hospital cost, we evaluated total hospital and intensive care unit length of stay for inpatients who expired compared to similar patients who did not expire during their hospital stay.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eWe conducted a retrospective propensity-matched cohort analysis of hospital inpatients who did and did not expire using de-identified data from 24 hospitals representing six health systems across the United States. In addition to demographic measures, the Rothman Index patient condition score was used to ensure cohorts were matched in physiologic acuity. Multivariable regression models were used to estimate the impact of mortality on the primary outcomes of total and ICU length of stay.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eMatched cohorts of patients who did and did not expire each comprised 6,129 patients. Patients who expired had longer mean overall hospital length of stay (LOS) compared to those who did not (13.3 vs 8.3 days, \u003cem\u003ep\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;0.0001) as well as longer mean ICU LOS (7.2 vs 5.7 days, \u003cem\u003ep\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;0.0265). Multivariable general linear models identified a 51% increase in predicted LOS and 33% increase in ICU LOS for patients who expired in the hospital.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eAs length of stay measures are routinely quantified in financial terms by hospitals, this work suggests it may be possible to translate mortality reductions into length of stay reductions as an inferential step in deriving a financial return on investment for mortality-focused quality of care initiatives.\u003c/p\u003e","manuscriptTitle":"The potential for in-patient mortality reductions to drive cost savings through decreases in hospital length of stay and intensive care unit utilization: a propensity matched cohort analysis","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-02-16 16:48:14","doi":"10.21203/rs.3.rs-3934554/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"editorInvitedReview","content":"","date":"2024-02-26T19:47:21+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"1d89513d-5d0d-4495-ab36-79ee1552fd3b","date":"2024-02-19T15:00:24+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-02-18T12:01:22+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2024-02-15T17:05:45+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-02-15T07:55:57+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-02-15T07:55:57+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Health Services Research","date":"2024-02-06T17:01:20+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
